JOHNL. DU FRANE, OF OAKLAND, CALIFORNIA. TAPE-PUNCHING REGISTER.

Specification of Letters Patent.

Patented Jan. 1, 1907 Application filed April 12, 1906. Serial No. 311,239.

To all whom it may concern:

Be it known that I, JOHN L. DU FRANE, a citizen of the United States, residing at Oakland, in the county of Alameda, State of California, have invented certain new and useful Improvements in Tape-Punching Registers; and I hereby declare the following to be a full, clear, and exact description of the same.

My invention relates to that class of punchin registers in which a tape is perforated and fe by means of devices set in operation by electrical impulses for any purpose which is subserved by such a record-as, for example, fire-alarms.

My invention has for its object the simplifying of the construction of the machine, with its consequent advantages of economy in manufacture and accuracy in operation.

It has also the further object of providing a machine which is automatically set by its own operation, so that it does not require any attention toj-jjrepare it for use initially or to keep it so prepared.

These objects are attained by making both 2 5 the punching operation and the power required for the feed of the tape the direct and immediate result of the pressure of the armature-bar under the electrical impulse in contradistinction to the common practice of 3 making the armature-bar serve only the initial function of liberating a previously-set device, such as a clock mechanism under the control of a wound-up mainspring.

To this end my invention consists in the 3 5 novel machine w 'ch I shall hereinafter describe and in the novel construction, arrangement, and combinations of its parts, as I shall fully point out.

Referring to the accompanying drawings, which illustrate my invention, Figure 1 is a side elevation of my tape-punching register. Fig. 2 is a plan with the tape-roll removed. ig. 3 is a section on the line mm of Fig. 2. Fig. 4 is an end view of the machine.

1 is a base to which a frame 2 is secured. Te a pivot-shaft 3 in the top of the frame is clamped or otherwise fitted the bar 4 of an armature 5, operated by an electromagnet 6.

Rising from the base 1 is a post 7, to which is secured the tape punching and feed table 8. In a bracket 9 of the post 7 is mounted the unch 10, controlled by a spring 11,

WlllC spring bears between the lower arm of the bracket and an upper stop 12, mounted adjustably upon the punch by a set-screw 13, whereby its tension may be suitably varied. This stop has a guide-pin l4 extendin through the upper arm of the bracket an serving to steady the punch in its verticallyreciprocating movement. Through the armature-bar 4 is fitted adjustably a contactpin 15 in the form of a screw which is adapted to bear upon the upper end of the punch and to operate said punch by forcing it down. Rising from the frame 2 is the reel-bracket 16, in which is mounted the tape-roll 17. The tape T from this roll passes down over a guide-roller 18 in the lower part of the reelbracket, then through an opening in the armature-bar 4, and under a uide-roller 19, by which it is directed upon tlie punching-table 8, and beneath the lower arm of the punchcarrying bracket 9, and thence forwardly upon said table to the feed-rolls. The lower feed-roll 20 is a toothed one, playing up through an o ening in the table. The upper or presser rol 21 is a smooth-surfaced one earned by an arm 22, pivoted at one end to the post 7 and having attached to its other end a spring 23, by which the Presser-roll is held down on the tape with the proper pressure. This ressure may be regulated by attachin the ower end of the spring 23 to a short s aft 24, upon which it may be Wound to increase its tension or unwound to decrease it.

Mounted in the frame 2 is a rock-shaft 25, having a crank 26, with a pin 27. U on this pin is fitted the forked lower end 0 a connecti -rod 28, the upper end of the rod being suitab attached to the armature-bar 4. Upon t e rock-shaft 25 near one end is fixed a grooved crank 29, best formed in the shape of a pulley-segment. To this pulley-crank is attached one end of a sprin 30, the other end of the sprin being secure to a turnable pin 31, by whic the tension of said spring may be suitably regulated.

Fixed upon the shaft 25, by an arm 32 is a spring-controlled pawl 33, which engages with a ratchet 34 on the side of a large gear 35, which is loosely mounted on the shaft 25. The large gear meshes with a pinion 36 on a shaft 37, which carries the lower or toothed tape-feed roll 20. The shaft 37 also carries a gear 38, which meshes with a pinion 39 on a shaft 40, carrying the escapement-wheel 41,

with which engages the escaipement-pawl 42 on a shaft 43, carrying an a ustable pendulum 44.

The operation of the machine is as follows:
